MoUntIng consIdeRAtIons

Before installation read and follow the Safety Practices on page 3. Failure to follow these safety practices could result in death or serious injury.

READ AND FOLLOW THE OPERATION INSTRUCTIONS IN THIS MANUAL BEFORE OPERATING THE VEHICLE RESTRAINT. If you do not understand the instructions, ask your supervisor to teach you how to use the vehicle restraint.

Improper installation of the vehicle restraint could result in death or serious injury to dock workers or other users of the vehicle restraint.

Place barricades around pit on dock floor and drive while installing, maintaining or repairing vehicle restraining device.

Be certain bystanders in the driveway stand clear when vehicle restraint is operated.

Be certain to follow the installation instructions in this manual.


1. The dock face on which the vehicle restraint will be mounted must be flat to prevent binding of the mechanism. If the dock face is not flat it may be necessary to use shims or physically modify the dock face to provide a flat mounting surface. If shimming is required it is necessary to shim behind the pivot pin as well as at the anchor bolts.

Vehicle restraints require a 4" bumper projection from the

front of the bumper to the rear of the back plate of the restraint (the mounting surface). Less than 4" of projection can allow vehicle RIG to damage the restraint. Some lip saddle type dock levelers may require modifications – consult factory.

2. The standard anchors provided with this product may only be used on docks constructed of solid concrete. For mounting to block walls refer to Service Bulletin #1023. Docks constructed with other materials require special mounting consideration. Contact your local Kelley distributor for information.

3. Docks 46" and lower may require a specially modified vehicle restraint or operation of the dock leveler may need to be restricted. Contact your local Kelley distributor for information.

4. A 3/8" min. gap is required between the dock leveler front frame and pit floor to install the horizontal mounting plate.

5. Do not install the vehicle restraint anchor bolts into aged or unsound concrete.

If the driveway beneath the vehicle restraint is affected by frost heave:1. Raise restraint sufficient distance to prevent damage, or2. Modify driveway to provide additional clearance.

Consult registered architect or professional engineer.

InstAllAtIon, continued

wedge AnchoR InstAllAtIon (stAndARd InstAllAtIon)


Use standard anchors on smooth 4,000 PSI concrete walls only. For aggregate, cinder block or tilt walls - consult factory.

Oversized holes in the base material will make it difficult to set the anchor and will reduce the anchor’s load capacity.

Do not use an impact wrench to set or tighten the wedge anchors.

1. Using a 1/2" diameter bit, drill a hole into the base material to a depth of at least 1/2" deeper than the embedment. The minimum embed depth of the 1/2" anchor is 3-3/8". The tolerances of the drill bit should meet the requirements of ANSI Std. B212.15.

2. Blow the hole clean of dust and other material. Do not expand the anchor or screw the bolt in the anchor assembly prior to installation.

3. Drive the anchor through the fixture into the anchor hole until the bolt head is firmly seated against the fixture. Be sure the anchor attains the minimum embed depth of 3-3/8".

4. Tighten the anchor by applying 40 ft. lbs. torque. See Fig 1.

Do not install, operate or service this product unless you have read and followed the Safety Practices, Warnings, and Installation and Operating Instructions contained in this manual. Failure to do so could result in death or serious injury. ALWAYS USE DOCK LEVELER SUPPORT WHEN WORKING UNDER A DOCK LEVELER RAMP OR LIP.

Place barricades around pit on dock floor and drive while installing, maintaining or repairing dock leveler.

Improper installation of anchoring devices or installation into aged or unsound concrete could result in death or serious injury.

1. Insert the horizontal mounting plate into the gap between the dock leveler front angle and the pit floor.

note:When used with older style Kelley Mechanical “MK” or “K” series and Kelley Hydraulic EHD 60,000 lb. capacity dock levelers, the mounting plate must be mounted to the left of the dock leveler centerline as shown in Fig. 2. This off-center mounting is to allow for dock leveler spring adjustment and to prevent interference with lip rod lugs. For other dock levelers the horizontal mounting plate may be centered with the dock leveler. See Fig. 3.

If the horizontal mounting plate cannot be used, the top portion of the vehicle restraint must be welded to the dock leveler front angle and additional anchor plates installed to fasten the dock leveler subframe securely to the pit floor. A dock leveler reinforcing kit Kelley part number 901-323 is available for this purpose. Recommended reinforcing is illustrated on page 28.

2. Check access to the horizontal mounting plate anchor holes. A minimum of four (4) anchor holes spaced across the plate must be accessible. Drill additional 9/16" diameter anchor holes through the mounting plate if required. See Fig. 4.

Inadequate lifting equipment or practices can cause a load to fall unexpectedly. Make sure the lifting chain or other lifting devices are in good condition and have a rated capacity of at least 500 lbs for the lifting angle used. Never allow anyone to stand on or near the restraint when it is lifted or positioned. Stand clear of the vehicle restraint when it is positioned. Failure to follow this warning can allow the restraint to fall, tip, or swing into people, causing death or serious injury.

3. Place the bottom edge of vehicle restraint 1/2" above the driveway and align the backplate with the horizontal mounting plate. See Fig. 5. If the driveway is affected by heaving from frost, follow NOTICE on page 4 to prevent damage from the driveway movement.

4. Tack the vehicle restraint to the horizontal mounting plate using the tabs on the front of the plate. See Fig. 5.

5. Pull the vehicle restraint and mounting plate away from the dock and weld the full width of the horizontal mounting plate with a 1/4" fillet weld on the top side. Paint welded area to prevent rust. See Fig. 6.

6. Slide the vehicle restraint mounting plate assembly back into position on the dock. See step 1, page 6 for location. If shimming is required it is necessary to shim behind the pivot pin as well as at the anchor bolts. The pivot pin is shimmed to prevent bending the back plate if the pivot area is struck. The pivot pin area must not be fastened but left free to float.

7. Before anchoring vehicle restraint, operate the dock leveler with the vehicle restraint in its intended mounting position. Check that the vehicle restraint does not interfere with below dock operation and that the pendant dock leveler lip does not support the weight of the dock leveler on any part of the vehicle restraint. Operate in the below dock and dock level end load position with the lip pendant and with the lip extended. Store the dock leveler several times to be sure the pendant lip does not come to rest supporting the weight of the dock leveler on the vehicle restraint. Readjust mounting position as required. The vehicle restraint may be moved such that the horizontal mounting plate is up to 12" off center.

Improper installation that allows a pendant dock leveler lip to be supported by the restraint could result in death or serious injury. It is sometimes necessary to install lip deflector plates as indicated in Fig. 7 to avoid any chance of the pendant lip storing on top of or behind the backplate. Materials supplied by installer.

Anchors must be installed in a minimum of six (6) back plate mounting holes. The anchor bolts should be installed as the holes are drilled to prevent the vehicle restraint from shifting.

The anchor bolt heads must be tight against the back plate to prevent interference with the hook arm and gas spring.

8. Anchor the vehicle restraint back plate to the dock face using the anchors provided. The anchor bolts must be torqued to 40 ft-lbs to achieve maximum holding strength. See Fig. 7 and wedge anchor installation instructions on page 5.

9. Anchor the horizontal mounting plate to the pit floor using the concrete anchors provided with the vehicle restraint. The anchor bolts must be torqued to 40 ft-lbs to achieve maximum holding strength. A minimum of (4) anchors across the plate must be used. See Fig. 8 and wedge anchor installation instructions on page 5.

10. Move the hook up and down to be certain the hook does not bind on the track. Washers on the pivot pin may be moved from front to rear or vice versa to shim hook in or out as required. See “PARTS REPLACEMENT INSTRUCTIONS - Hook and Gas Spring” on page 25 for instructions on how to remove the hook to gain access to the rear shim washers.

RestRAInt eRRoRsMatch the PLC LED display with the chart to determine the error that has occurred and check the corresponding equipment for problems.

When the PLC is in Jog Mode, the restraint will raise or lower only while a button is pressed and will stop when the button is released. Jog Mode is entered when a failure to find LS1 while lowering has occurred. Use this to position the restraint, but disconnect power before attempting to make adjustments.

If the vehicle restraint fails to release, the RED light on the control panel will remain flashing. If the hook is jammed on the trailer, back the trailer to free it, then press and hold the ReleAse button until the hook is properly stored.

hook ARM And gAs spRIng1. Remove BLACK cover.

2. Disconnect linear actuator rod from lever. If linear actuator rod is not retracted it is necessary to push down on the hook to release tension on linear actuator linkage.

3. Hold hook arm down and remove top spring pin.

4. Slowly release the hook arm to allow the gas spring to fully extend.

5. Support the hook so that it does not fall when the gas spring is removed. Carefully pry the gas spring off of the ball stud on each end of the gas spring.

6. Remove the klipring from the pivot pin.

7. Disconnect actuating linkage.

8. With the hook in its highest position, carefully slide arm from pin.

9. Reverse above sequence to replace parts. Lubricate the following parts: pivot pin, ball studs, and linkage pivot pins.

AdjUstMentshook ARM AdjUstMent1. The hook arm may require adjustment if the linear actuator

is fully retracted and the gap between the hook arm and the lower spring pin on the T-rail is greater than 1/4". If this occurs, loosen the jam nut on the hook actuator leveler and then turn the socket head cap screw counterclockwise until the hook arm is 1/16" from the spring pin shown. Verify LS1 is made (LS1 senses the stored position of the hook arm by sensing the position of the gas spring). LS1 is made when PLC input 1 is off. If it is not made, loosen the two screws that hold the switch to the back plate and then rotate the switch clockwise until PLC input 1 turns off. Cycle the restraint returning it to the stored position. The hook arm and LS1 switch have been properly adjusted when the following are true upon restoring the restraint: LS1 is made (PLC input 1 goes off), the linear actuator does not bottom out (not fully retracted) and the gap between the hook arm and the lower T-rail spring pin is 1/16"-1/4". Repeat adjustments until the above is true.

Pivotshaft

Fig. 25sensoR bAR swItch AdjUstMentThe operation range for RIG sensing of the vehicle restraints is from 11" to 30" above the drive. If the 11" minimum specification cannot be achieved, the proximity switch cam and sensor bar have come out of adjustment. When properly adjusted, a slight (about 3/16") deflection of the sensor bar will turn the proximity switch LS4 on. Readjustment is accomplished as follows:1. Loosen the socket head cap screw that locks the proximity

switch can to the pivot shaft. See Fig. 25. This screw is located in place at the factory with Loctite 222 and may have to be heated to loosen the Loctite and prevent breaking the screw.

2. Apply Loctite 222 to the screw threads. Keep the sensor bar up against the bottom of the hook and rotate the proximity switch cam counterclockwise until the proximity switch turns on and then clockwise until the switch just turns off. At this position tighten the socket head cap screw to 60 inch pounds.

Check to make sure that the proximity switch LS4 does not turn on until the sensor bar is deflected slightly. Readjust the cam as necessary to achieve a slight (approximately 3/16") deflection of the sensor bar before the proximity switch turns on.

Stepping on the sensor arm or otherwise manually deflecting the sensor arm farther than possible in normal operation can cause this out of adjustment problem.
